SEOUL—Korea Gas Corp. (KOGAS) will receive its first LNG cargo in early July under a long-term supply deal with U.S. exporter Cheniere Energy Inc. (NYSE MKTS: LNG), two sources at the South Korean company said on June 23.

The 74,000-tonne LNG cargo was loaded from Cheniere’s Sabine Pass, La., export terminal and is scheduled to arrive at the port of Tongyeong, South Korea on July 2, one of the sources said. Both sources declined to be identified.

The 20-year supply deal, under which KOGAS will receive 2.8 million tonnes of the supercooled fuel per year from Cheniere, had long been expected to kick in this year, but its exact start time was not known in markets.
